A class has 24 students, 9 of whom are girls. What percent are girls?

Explanation:
Percent is a way to describe part of a whole as a number out of 100. Here, you have 9 girls out of 24 students. Write this as a fraction: 9/24, which reduces to 3/8. Turn that into a decimal: 3/8 = 0.375. Convert to a percent by multiplying by 100: 0.375 × 100 = 37.5%. So, 37.5% of the class are girls. You can check by thinking that 1/8 of the class is 12.5%, so 3/8 is 3 × 12.5% = 37.5%.
